GUN-SIGHT.

' Specification of Letters Patent.

Patented NOV. 28, 1905.

To all 2071/0511, t may concern:

Be it known that we, JOHN Y. BASSELL and FRED C. BLENKNER, citizens of the United States, residing at Columbus, in the county of Franklin and State of Ohio, have invented a certain new and useful Improvement in Gun- Siglits, of whichthe following is a specification. I

Our invention relates to a new and useful improvement in gun-sights.

The object of the invention, essentially, is to provide a gun-sight so constructed'and arranged as to meet the many requirements necessitated by the varying visual needs or desires of different gunners.

A special objectof the invention resides in a movable hood whereby all the advantages obtain-ed' by a globe, a ring, or an open sight are attainable.

Further features of novel combination lie in the hinged reiiector and an interchangeable and reversible sight-piece.

Finally, the object of the invention is to provide a device of the character described that will be strong, durable, and eiiicient, and one in which the parts may be so positioned vor adjusted as to produce at pleasure most any form of gun-sight that the gunner may demand.

Vith the above and other objects in View the invention consists of the novel details of construction and operation, a preferable embodiment of which is described in the specification and illustrated in the drawings, wherein- Figure 1 is a rear elevation of the gun-sight. Fig. 2 is a side elevation. Fig. 3 is a front elevation. Fig. 4 is a top plan view with the sight-piece removed. Fig. 5 isa longitudinal vertical sectional view taken on the line .fc of Fig. 1. Fig. 6 is a top plan view showing the sight-piecein place. Fig. 7 is a longitudinal vertical sectional view taken on theline y g/ of Fig. 1. Fig. 8 is a front elevation of a modified form. Fig. 9 is a rear elevation ofthe same. Fig. 10 is a side elevation of the modified form. Fig. 11 is a plan view of the same with the sight-piece removed. Fig. 12 is a longitudinal vertical sectional view of the modified form, and Fig. 13 is a detail elevation of one of the sight-pieces.

In the drawings the numeral 1 designates the base, which is suitably formed to be read- ".ily secured upon thegunbarrel. The base is formed with upwardly-extending side walls 2,

between which extends the concaved `recess 3,

Sight.

which is covered by the circular housing 4, whose inner periphery conforms with the recess 3 to form a perfect circle. The housing 4 extends over the forward portion of the base only and terminates at its rear end flush with the sight-piece groove 5, which extends transversely of the base. A removable and reversible sight-piece" 6 is adapted to fit in and completely fill the groove 5, having its outer ends shaped to conform to the contour of the vertical walls 2 and provided with locking-recesses 7, extending upward from its bottom, which engage over the fixed pin 8 and ithe locking-pin' 9. The locking-pin 9 is formed with a shoulder 10, which engages with the spring-latch 11 when the pin is withdrawn to prevent its disengagement from the base. The latch normally engages in an annular recess 12 of the pinto hold the same in its locking position. The sight-piece 6 is formed with inwardly-curved' lips 13, which aline with the longitudinally-extending guides 14 of the walls 2. The guides 14 are so arranged as to form ways into which project the laterally-extending feet 15 of the slidable hood 16. The hood 16 is formed to fit the outer contour of the housing 4 and to completelyfl'l thespace between the said housing and the guides 14. The hood is formed with a downwardly-extending angular flange 17, which impinges the rear end of the housing 4 when the hood is in its forward position, thus providing a guard which prevents the disengagement of the hood from the housing. The outer surface of the hood is roughened, as shown at 18, to provide a gripping-surface whereby the hood may be readily moved backward and forward in the guides 14 and the lips 13 to form either a ring-sight or aglobe- Guard-plates 19, secured to the rear face of the base by screws 20, cover the rear ends of the guides. 15, thus acting as stops to limit the rearward movement of the hood. It will be readily seen that by moving the hood rearward, as shown in Fig. 5, what is known as a globe-sight is produced and that by sliding the said hood either forward or backward globes of various lengths may be had and thatthe amount of light admitted upon the si, ;htpieceA is modulated. When the hood is moved -to its forward position, as clearly shown in Figs. 2 and 4, the sight-piece is entirely exposed to the light, and all the.

effects of what is known as a ring-sight are obtained. It is to be observed that by sim- IIO . or set with a jewel piece 6 may be lifted out of the groove '5, reversed, again inserted in the said groove, an the pin shoved forward, thus locking it in place, and a different sight point or center being presented to the eye, as each sight-piece may be designed with different forms of sightcenters on opposite sides, as clearly illustrated in Fig. 5, and by manipulating the hood 16 various light effects may be produced at the pleasure of the gunner and to suit the various climatic conditions. In order to assist in the lighting of the sight-center, we arrange upon the rear end of the base a refiector 21, which has its back concaved to tit the contour of the recess 3, and thus when in its folded position presents no obstruction to the vision of the gunner. This reflector is formed with a fiat face 22, which is polished or coated with a refiecting material, so as to readily reflect the light and illuminate the sight-center 23 of the sight-piece 6, which is preferably polished or brilliant material, such as gold and silver, which when illuminated by the rays of light directed upon it by the refiector becomes luminous. This sight-center is preferablyT arranged at an angle, so as to readily receive the refected rays, and when the sight-center 23 is concaved it will tend to gather the rays of light cast upon it by the refiector. It is to be understood, however, that various forms of sight-pieces may be employed with the reflector, which acts to give to the sight-center it true color value, which is destroyed where light is excluded. The reflector is pivotally mounted upon a pin 24, which is supported by'hinge-lugs 25, projecting from the base 1, and is also provided with notches 26, in which the head of a springpressed plunger 27, arranged in a recess 28 of the base, engages. The notches are so disposed that they engage with the plunger-head 27 when the reflector is in its extended position, as shown in Fig. 5, and when it is in its closed position, as shown in Fig. 4. It will thus be seen that an accidental opening or closing of the refiector which might result from the recoil of the gun is obviated and that the said reflector is maintained in the desired position.

In Figs. 8 to 12, inclusive, we have shown a slightly-modified form of sight, in which the housing 4 is omitted, as Well as the guardfiange 17 and the hood 29 slightly elongated. In the modified construction the forward portion 30 of the base 1 is slightly elongated, so as to accommodate the lengthened hood. The base l is formed witha recess 3, like the recess 3, but having less depth than the said recess. The hood 29 has its inner periphery conforming to the contour of the recess 3, so as to form therewith a perfect circle. The hood is formed with angular laterally-extending feet 31, which fit in the guideways ofthe 2uides 32, which extend longitudinally of the ase.

For the purpose of making the hood 29 removable, so that what is known as an open sight may be had we provide in thefront wall of the base notched headed screws 33, which are so disposed aswhen turned, as shown in Fig. 8, to abut stop-pins 34 and stand in the path of the feet 31, thereby constituting stops for preventing the accidental displacement of the hood from the guides. However, when it is desired to entirely remove the hood the screws are given a quarter-tu rn, which causes their notched portions to lie under the ways of the guides 32, thereby unobstructing the same and allowing the hood to be withdrawn from engagement therewith. The other parts of the modified form are constructed and arranged like those of the preferred form which have been fully described, and it is therefore thought that a second description of the same is unnecessary.

It is to be observed that when the hood 29 is in the position shown in Figs. 10, 11, and 12 all the effects of a ring sight are produced, and that by sliding the hood rearwardly, so as to cause it to stand over the sight-piece, a globe-sight is produced. Therefore by constructing a gun-sight in this manner one is enabled to readily produce either an open sight, a ring-sight, or a globe-sight, and by employing the reflector he is enabled to illuminate the sight-center, which becomes luminous. This illumination of the sightcenter also restores the -color value thereto and greatly aids in the accuracy of the sighting. In some instances it will not be necessary or desirable to use a rcfiector, but under certain conditions it may be found that the reector is a most convenient and necessary accessory.

Having now fully described our invention, what we claim, and desireto secure by Letters Patent, is-

1. In a gun-sight, an interchangeable sightpiece, a movable hood, and a reflector.

2. In a gun-sight, the combination with a base having guides and an interchangeable sight-piece, of a hood movable in said guides, and a reflector.
